.Beit known that l, JAMES EBN-nerr JOHN? son, a subject of the King otGreat Britain and 'Ire-land, and residingjat. Soho tron.

Vorlifs, Bolton, in the county of Lancaster, England, have inventedcer-tain' new and useful ,Improvements in and Relating tov Steam,Gondensera Feed-Tater -Heaters,`r`

and the like, of which the iollow-ingA isa 10 specification.

This invention rela-tes toV doors or end' closure means for isteanril`condenser, feed heater and the like units and has for its object theprovisionrofA means for faciliitat in-g theopening andclosing ofthe-door or end'closureof a'condenser or :teed heater.`

'The inventiony is particularly applicable to that type :ofcondenser orv*feed heater having end boxes: comprising two parts and:

the centre line or diameter` forming two parts or doors whichvare hingedand adapta;

ed toopen outwardly.

Doors of thisftype are usually '.used 1n .This effect may be attained bydisplacing the pinV upon-.which the door is hinged with referencel totheseating ofthe door 40r by displacing thelldoor withv reference totheaxis of a ixedhinge and with respect tothe seatingV of; the door, -or afixed hinge pin may be employedand means l.provided A:which the. doorhinges inopening o r closing.

`Furtherfeatures ofthe invention'will be hereinafter describedfandde'med in the claims. --r In the accompanying drawings: t i

Figure'i is an enlarged section showing the slots and studs orsecuringthe inner: sides of the doors .to their seating shown in i In `carryingthe-'invention into' effect ac 'cording to one. convenientjmodeasapplied to a condenser of circular crosssection, the

end closure is divided upon the vertical die:

vameter formingtwo doors land 2, eitheriof be 'opened independently ofthe Y which may other. j v The circular peripheral edge Sfo the doorsand thefedge of each'adjacent the centre line or ver-tical diameter areprovided` l with orifices-6 or slots/7 for' the insertion" ofthe usualVbolts or -studs for screwing home the doors when in position and thecircumferential periphery VVmay have the usual forcing boltsfor'pressingoff thedoor" from its seat." l r' 1 VEach door is providedwith means where-lf'Y by it may be vmounted upon apair of .fixed hingepins 8 common to both'doors mounted` upon `a' support 9 carriedfby thecondenser or' other fixed part. These pins vE5 are locatedxi'n thecentral vertical plane'of thev condenser or adjacent "the verticalcentre line or diameter of the unitv and-preferably aboveV and below theextremitiesfofthe fver'- tical diameter. ,v l .t

Each hinge pin has rotatably ymounted uponV it two-"eccentric :bush or.sleevemem- 'bers' vl0 andv 1'1` one'tot which (preferably` theioutermember 10) 'may be mountedupon" a circular sleeve or concentricpart,-orfeX,-"4 tension lltL of 'the' other. member 11. s-"L'Ihe outerends of the` eccentric 1- bushv members arev providedwith means such "asorices ltlauandllb. for A the insertion oftommy bars for the Apurpose'of-ie1iabliiig.'the eccentric bushes vto' be rotated about 'the-hingepins 8?. 'i

The door sl and 2 may 'be-each 4pr'c'ivid'ed. with. a'Y pair of'brackets ,12 and '13, onei/located at the upper side and the otherlocated at the lower `vside of thel door.,v These brackets l2 'andflareadapted'to terminate in rings orihousings liQseandV 15%4 which areVmounted uponV 1 the respective eccentric cofY bushes l1 and v10 sothat-'relative rotary movement may A set screw 14 may be provided.ineach of the housings and adapted to cofoperate with an arcuate slot l5in the eccentrics for the purpose of preventing axial movement of theeccentric member and of limiting the rotary movement ofthe latteny Forthe purpose o-f lubrication, grooves, channels or ducts may be formed inor upon the hinge pins, eccentrics and rings or housings, so that oil orother lubricant may be supplied and distributed upon the workingsurfaces.

This arrangement of fixed hinge pin, eccentric and housing enables thedoors and particularly thoseparts (such as la and 2a) adjacent thevertical diameter of the condenser, to be displaced with respect to theaxis of the ixed hinge pins 8, so that the part in question may be movedaway from its seating 16 to provide clearance in opening up or may bemoved towards the seat to diminish the clearance inclosing the door. f y

It will be appreciated that if no displace ment of the door adjacent thehinge took place when a door wasopened and caused to hinge about theaxis of the fixed hinge pin, the inner edge of the door adjacent theaxis of movement travelling on the arcof a circle would scrape or rubthe "surface against it was bedded which would cause a wearing orscraping olf of the joining or packing material employed.

Further, it will be observed vthat when a door was closed under suchconditions by Vmoving it about its hinge, a similar scraping actionwould take place and when the door had been shut it would be impossibleto screw up firmly the studs (see Figure 4) to close the door along theedge adjacent the hinge without straining the hinge, as the fixed axiswould provide no play or scope for the movement which would be requiredto permit the tightening of nuts on` the securing studs. Y

In operating a structure according to the present invention, the nuts ofthe securing studs (Figure 4) and the securing or seal-- ing bolts areremoved from the holes 6. The forcing off bolts on the circumferentialedge are manipulated and at the same time the eccentric bushes 10.corresponding to the door which is to be opened (say, for example, thedoor l) are rotated by the operationvof a tommyV bar or other means. Therotation of the eccentric bushes displaces the edge of the door laadjacent the vertical diameter towards the axis of the fixed pin 8 to arequisite extent to provide the necessary clearance. The door may thenbe rotated about its eccentric bushes with the usual hingingy movementand will swing clear of `its seating 16.

In closing,l the door is swung to and hinges upon the correspondingeccentric bushes. lVhen the door has thus been brought approximatelyinto the closed p0- sition its eccentrics 12al are again operated` butthis time ina manner to cause the part Vof the door la adjacent thehinge to be moved on to its seating 16. The operation of the eccentricsin this casemay be c0m-y pleted as the securing bolts and nuts of thestuds are screwed home, so that the required ly withv facility andwithout injuringthe` packing or seating.
